A Thai-and-English System One model. Qwen3.5-0.8B continued-pretrained on about 5B Thai tokens, its language-model head replaced by a 256-way slot head (slot 255 abstains), trained on 2–3M decision examples and temperature-calibrated per question type.
Together AI's Jev-style classifier. A LoRA fine-tune of Qwen3.5-4B that reads a state, a question and 2 to 24 options and returns one option letter. Served on Together's platform; recipe published.

Questions
What is the difference between openthai-systemone and tev1?
openthai-systemone is from iApp Technology and tev1 from Together AI. openthai-systemone has open weights you can download and run; tev1 has open weights and a hosted API. Both answer choice, classify and route questions. Only openthai-systemone answers score and noul. openthai-systemone is the smaller model, at 800M parameters to 4.0B. openthai-systemone is licensed apache-2.0; tev1, other.
Which is more accurate, openthai-systemone or tev1?
They report on different suites — openthai-systemone 74.3% on Bespoke public subsets (13, macro average), tev1 88.0% on Together development set (reused, not held out) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, openthai-systemone or tev1?
openthai-systemone: Free (open weights). tev1: $0.042 / $0 per 1M, or free to self-host. Open weights cost nothing per call beyond your own hardware.
Can I run openthai-systemone or tev1 locally?
Yes, both: systemone pull iapp-technology/openthai-systemone and systemone pull together-ai/tev1 download the weights.
